Depolarization
|
Explanation:
Detailed explanation-1: -Repolarization occurs when the K+ channels open and K+ moves out of the axon. This creates a change in polarity between the outside of the cell and the inside.
Detailed explanation-2: -During neuronal polarization, a spherical cell develops into a highly-compartmentalized cell with clearly defined borders between dendrites and the axon. The underlying signaling pathways generate a high morphological and molecular contrast between dendrites and the axon.
